Board 0002 cannot observe output from IC34 to OUT_RAW_3_P
The trigger unit output has the following datapath:
- flip flop cleaner
- delay line
- 1:2 fanout ADCLK925BCPZ, (this is IC34 for trigger unit 1 on RF channel 2)
- goes to a mux
- goes to a pulse shaper then a mux
- Mux -> front panel sma
We can only observe an output signal when selecting the pulse shaper input to the mux.
Probing IC34, we found nothing on pins 11+12, but the signals were good on 9+10 which confirms our observations from the front panel sma
